hi, I have a quetsion in java for byte datatype does '0' correspond to true and '1' to false or vice versa thanks > hi, > I have a quetsion in java for byte datatype does '0' correspond to > true and '1' to false or vice versa Neither. The boolean type is not directly convertible to char or any other Java integer type. graniteraju@gmail.com schrieb: > hi, > I have a quetsion in java for byte datatype does '0' correspond to > true and '1' to false or vice versa > > thanks I'd say neither, if I got you right. byte is a number valuetype that ranges from -128 to 127 (or was it -127 to 128?). For true and false you have the valuetype boolean. However, you are free to encode true/false by using a byte, but I would not suggest this.

Consequently operations between scalar types and booleans are not possible. -- Mike W > hi, > I have a quetsion in java for byte datatype does '0' correspond to > true and '1' to false or vice versa If you're looking for a datatype to represent true and false, you should probably use boolean, not byte. A boolean can only be true or false. Other responders have told you what the byte datatype can hold. -- Rhino Free MagazinesGet these publications absolutely FREE for up to 12 months.
